I show that habit formation is an important determinant to the dynamic transition of the economy. Furthermore, I identify conditions that chaotic motion may occur. When habits last only for one period, the dynamic transition of the economy can be characterized by a one-dimensional dynamical system and the possibility of Li-York chaos is studied.When habits last for periods, the economy is represented by an -dimensional dynamical system (a high-dimensional dynamical system if ). Since Li-York chaos is only defined in a one-dimensional dynamical system, the possibility of chaotic motion in the horseshoe structure and entropic chaos are studied for and , respectively.貨幣持有模型混沌動態預期持續偏好。Cash-in-advance economyChaosExpectationPersistent habits.
